| How to Use a Jadeite Filter |

| Label | Description | Instructions |
| 1 | Jadeite Filter | Hold your jadeite filter up over the gemstone(s). I recommend not holding it directly up to your eye, but keeping it about six to eight inches away. |
| 2 | Light Source | Aim a strong light source at the gemstone(s) . Note that the light source should not be aimed through the gemstone(s) into the jadeite filter, that will not work! You must aim the light into the gemstone and it must be strong enough to come back out of the gemstone into the jadeite filter for it to work properly. And it must be strong enough to get some light to pass through the filter itself which is also no small feat. I use a fiber optic light and it works great. In a bind, a flashlight or bulb will work but I get eyestrain that way. |
| 3 | Gemstone(s) | Have the gemstone(s) underneath the filter and in the path of the strong light source. I prefer to lay the stones down on something that is bright white to help with light return. |
| Assembly Complete | Identify Gemstone(s) | There are many different color properties that can be exhibited by gemstones through the jadeite filter. Some gems even have different colors based on the locality where they were found. Above I used the simplest test as an example. The gem rough above is green tourmaline. The jadeite filter displays the stones are red, not green, which means that the green tourmalines contain chromium. With that information in hand, they can be called chrome tourmaline and their value goes up! I recommend purchasing the book Gem Identification Made Easy to help you learn the many different ways the gemstoe color properties through a jadeite filter can help you determine what kind of stone you have. Remember that the color identification is diagnostic, but not conclusive. |
| Disclaimer | CYA! | I am no expert! I use these tools as best I can, but I am not a graduate gemologist by any means. I try to keep it simple as much for me as for you, so please use this as a starting point and when you get in deep, consult your books and experts. Thanks! |
